Michael; yes the Imagon came complete with disks, and I'll be using it on a 4x5 Technika.

David; et all,...through another forum, I received a .pdf file with some basic instructions for using the imagon. Please contact me should you wish to have it forwarded to you.

Jon; of course I will learn to use this lens, with or without instructions, but the fact remains that it is a rarely (today) used design, and so without written information, the learning curve will initially be a little steeper.
